T (LZ/f Hill/ont 'it 77mg/ con/00ML:

Be it known that I, JAMES ALBERT LONG, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Hose-Nozzles; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in hose nozzles.

The object of the invention is to provide a nozzle of this characterparticularly adapted for use in connection with :lire-hose and havingmeans whereby the stream passing from the nozzle may be regulated forshort or long distance work.

Wvith the above and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be hereinafter described and claimed.

In the accompanying drawings :--Figure 1 is a side view of a nozzleconstructed in accordance with the invention, parts of the same beingbroken away to disclose the construction of the nozzle; Fig. 2 is alongitudiual vertical sectional view of the nozzle, showing the reducingcone projected and its parts in position for throwing a smalllong-distance stream; Fig. 3 is a similar view with the reducing coneretracted to permit the nozzle to throw a large stream of water a shortdistance; Fig. 4 is a detail side view of the reducing cone, showing'the parts expanded; and Fig. 5 is a transverse, vertical sectional view,on the line 5--5 of Fig. 1.

Referring' more particularlyr to the drawings, 1 denotes the nozzle,which consists of an inner section 2 adapted to be secured onto the endof a hose, said section being' reduced or tapered to form aconical-shaped outer end 3. At the inner end of the conical-shaped orreduced portion of the section 2 is formed a series of exteriorscrew-threads 4 at the inner end of which is formed an annular shoulder5.

Adapted to be screwed upon the threaded portion of the section 2 andprojecting beyond the reduced end thereof is an outer section 6, saidsection having a tapered or conical-shaped outer end, which for aportion o' its distance extends substantiallyT parallel with the reducedor conical-shaped outer end of the inner section 2. On the inner end ofthe section 6 where the same screws upon the threaded portion 2 isformed an annular enlargement or shoulder 7 in which is formed a seriesof radially-disposal sockets S adapted to receive a Spanner wrench tofacilitate the screwing on or off of the section 6.

In the conical-shaped outer cud of Vthe section 6 is arranged a reducingcone 9 formed of a plurality of tapering sections or plates l 0, whichare brought together to form a conical-shaped sleeve or thimble adaptedto be slipped forwardly and rearwardly within the tapered portion of theouter section G. IVhen the cone 9 is slipped Aforwai-'dly or toward theouter end of the section 6, the parts of the cone will be drawn togetherand will project slightly beyond the outer end of the section 6 and willthereby reduce the size of the section 6 and cause the stream of waterpassing from the hose to be reduced and thus thrown to a greaterdistance. IVhen the cone 9 is drawn inwardly, the sections or parts 10of the same expand to fit the inner walls of the reduced end of thesection 6, thereby permitting the stream to be thrown from the hose tothe full size of the inner diameter of the outer end of the section 6,thus enabling the hose to throw a large stream for short distance work.In order that the cone 9 may be retracted and projected in the section 6of the nozzle, the cylindrical portion of said section immediately inrear of the tapered portion thereof is provided with a series ofbayonet-shaped slots 12, which are arranged at equidistant points aroundthe section 6.

Slidably and rcvolubly mounted on the cylindrical portion of the sectiono' is an operating sleeve or collar 13, in which is formed a series ofthreaded bolt holes 14, through which are adapted to be screwed coneoperating pins or bolts 15. The inner ends of the bolts project throughthebayonet slots 12 and engage apertures 16 formed in the inner end ofeach of the sections 1.0 of the cone 9, so that when the sleeve orcollar is turned in one direction the pins will be moved .in the forwardo'llset portions of the bayonet slots 12 into alinement 'with thelongitudinal portions thereof, at which time the sleeve or collar 13together with the cone-section 10 may be drawn rearwardly, thusretracting the same into the section 6 of the nozzle and permitting theparts of the cone to expand and increase the size of the dischargeopening of the nozzle` As soon as the movable parts of the nozzle havebeen retracted to bring the pins or bolts 15 opposite to the inneroffset .IOO

the operation of the same.

portions of the slots 12, the collar or sleeve 13 is given a furtherturn, which will engage said pins with said inner offset portions of theslots, thereby locking the same and the parts of the cone into aretracted position. 'Vhen the sleeve or collar 13 is turned in theopposite direction to disengage the pins from the inner offset end ofthe slot, said collar and the sleeve and the parts of the cone may bepushed forwardly, thus projecting said cone from the forward end of thesection 6 and reducing the size of the opening of said sections. Thecone is locked in its projected position by turning the sleeve or collar13 to engage' the pins 15 with the forward offset portions of thebayonet slots, as will be understood. If desired the outer surface ofthe sleeve or collar may be knurled or milled to facilitate The reducingcone 9 may be constructed of any number of sections, there being five ofthe same shown in the present instance, a bayonet slot 12 and anoperating pin or bolt 15 being provided for each of the sections of thecone.

By providing a nozzle constructed as herein shown and described, thesize of the stream thrown therefrom may be quickly and easily regulatedto enable the hose to be used for throwing a large stream to a shortdistance or a small stream to a longer distance.

From the foregoing-description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent, is

1. In a hose nozzle, the combination with an inner hose engaging sectionhaving a tal pered outer end, and an annular series of screw-threadsformed thereon at the inner end of said tapered portion, .of an outersection having an interiorly threaded inner end adapted Vto be screwedonto the threaded portion of said inner section, areducing cone formedof a plurality of tapering sections or plates arranged between saidinner and outer sections of the nozzle, an operating sleeve or collarslidably and revolubly mounted on said outer section, and pins or boltsarranged in said sleeve or collar and adapted to project through slotsin said outer section and into engagement with the plates of said cone,whereby the same are projected and retracted by said sleeve or collar,substantially as described.

2. In a hose nozzle, the combination with an inner hose engaging sectionhaving an annular shoulder and a tapered outer endd, of an outer sectionadapted to be screwed into engagement with the shoulder on said innersection, said outer section. having formed therein an outer series oflongitudinally-disposed bayonet slots, a reducing cone arranged in saidouter section between the inner wall of the same and the outer wall ofthe inner section, an operating sleeve or collar slidably and revolublymounted upon the outer section of the nozzlejY and a series of pinsarranged in said sleeve or collar and adapted to project through thebayonet slots in said outer section and into engagement with thereducing cone, whereby the latter may be projected or retracted,substantially as described.

ln testimony whereof l have hereunto set my hand in presence of twosubscribing witnesses.
